Abstract. E-learning is essential in some instances and, with the right approach, can produce a high level of knowledge. With the growing demand for e-learning, the problem of online education quality assessment is becoming increasingly im- portant. The paper singles out the advantages and disadvantages of online educa- tion for students, education institutions and employers, and analyses approaches to online education quality assessment in institutions of higher education. This assessment should be carried out based on a scientific methodology using modern tools of economic and mathematical modeling and information technology. The authors suggest that the quality of online education shall be evaluated from the standpoint of the project approach, with due regard to commercial, reputation, and strategic aspects, i. e. regarding an online education program (or a set of pro- grams) as an investment project and assessing the efficiency of the given project for its core participants – the higher education institution and its students. The obtained performance indicators will constitute the objective assessment of the quality of e-learning in a particular higher education institution. These indicators are the response of the socio-economic system to the quality of online education.

To estimate the values of the weight coefficients that define the importance of the opinions of target groups, the authors propose using a scheme based on Fishburn sequences. They also note that it is feasible to design a software appli- cation for assessing the quality of online education.

1 Introduction

A major challenge faced by most of the world’s economies is how to improve the qual- ity of management and the quality of produced goods and services to boost their com- petitiveness in the global market. However, it is impossible to meet the challenge with- out generating a higher return from education across the board and especially in the

field of higher education. Knowledge is the catalyst for the development of a modern economy and the main factor of production.

One of the forms of training is e-learning, which is now becoming more and more popular. According to P. Ginns and R.A. Ellis, “e-learning is a growing and important part of student experiences of learning at a university internationally” [1]. Q.N. Naveed et al. say that “the E-Learning usage is growing rapidly and being preferred over the conventional teaching-learning process in a big way” [2].

E-learning is characterized by both positive and negative sides. Recently, the quality of online education has been the subject of much debate. Nevertheless, e-learning is essential in some instances (for example, during COVID-19 or for physically chal- lenged people) and, with the right approach, can produce a high level of knowledge (for example, a second university degree for employed and highly motivated people). “As the recent coronavirus outbreak prompted universities to start shifting classes online either for a few weeks or for the remainder of the spring semester of 2020, e-learning and remote education have popped up as the magical alternative for in-person classes in the time of the COVID-19 pandemic” [3].

It should be noted that nowadays specialists are facing the need for lifelong learning, which is due to the high dynamism of the professional environment. To keep their com- petitive edge in the labor market, modern specialists with a degree have constantly to enhance and expand their knowledge, skills, and abilities. And, in the long run, this trend is likely to intensify further, while e-learning is the best choice for working spe- cialists.

With the growing demand for e-learning, the problem of online education quality assessment is becoming increasingly important. This assessment should be carried out based on a scientific methodology using modern tools of economic and mathematical modeling and information technology since information technology has become a seri- ous decision support tool.

A significant number of scientific works are devoted to the problem of assessing the quality of online education. For example, different approaches to identifying criteria for online education quality assessment can be found in the works of the following authors: D. Al-Fraihat, M. Joy, R. Masa'deh and J. Sinclair [4], A.I. Guseva and E.B. Vesna [5], D. Masoumi and B. Lindström [6], S.Y. Sergeeva and E.D. Obrevko [7].

Despite a significant number of works on the problems of assessing the quality of online education, this research area still requires attention. We believe that there is a need to create a methodology for assessing the quality of online education, with objec- tive and unbiased evaluation.

The objective of the paper is to analyze approaches to online education quality as- sessment in higher school and to propose an original approach to address the issue, which should form the basis for creating a software application for online education quality assessment in higher school.

2 The Advantages and Disadvantages of Online Education

Currently, institutions of higher education are introducing e-learning to expand their markets, reduce costs, and achieve more flexibility. E-learning provides its participants with several undeniable benefits, but it is not free of some essential drawbacks given in Table 1.

Table 1. The advantages and disadvantages of online education for students, education institu- tions, and employers.

Parties Advantages Disadvantages

Stu- dents

Time-saving (for example, for transpor- tation); cost-saving (transport and other expenditures); the possibility to combine work and learning; the accessibility of learning materials 24/7; the availability of education for physically challenged people; the possibility of individualiza- tion of the trajectory and content of learning.

Difficulty in choosing a training program;

learning materials may be of low quality;

during e-learning, difficulties may arise with understanding the material, especially it's a practical part; students’ low motivation can be a constraining factor for obtaining the nec- essary knowledge, skills, and abilities; insuf- ficient level of social communication skills.

Edu- cation insti- tutions

The possibility to expand the market;

broad market coverage; reduction of in- frastructure maintenance costs; the pos- sibility to collaborate with other educa- tion establishments, including foreign ones.

The problem of motivating students to com- plete the full cycle of training; the problem of checking the level of knowledge, skills, and abilities of students; the problem of confirm- ing the identity of students during learning and checking the acquired knowledge; high labor intensity of development of training courses.

Em- ploy- ers

The possibility of employee training on the job.

Lack of a clear understanding of the presence and level of graduates’ competencies.

3 Analyzing Approaches to Online Education Quality Assessment in Higher School

“E-Learning (EL) is explained as a network affinity group sharing their information, knowledge, proficiency, and conferring education to many learners geographically in the same or diversified. EL is learning and teaching online and sharing resources elec- tronically” [9]. “Quality in education can be understood as a set of attributes or charac- teristics, selected to evaluate the service, which affects customer satisfaction, either ex- plicitly or implicitly” [10].

(4)

Online education quality assessment is a complex task; this is due to its qualitative nature, which, in some instances, may lead to a certain degree of subjectivity. The prob- lem of assessing the quality of e-learning is complex and subjective. The success of this task will be determined by the comprehensiveness of the approach and the correct choice of criteria and assessment methods.

This case requires the application of a comprehensive approach. It is also necessary to take into account that changes in the external environment may require adjustments to the designed assessment algorithm. Over time, the assessment criteria should be ad- justed and adapted to the requirements of the current period.

As M.G. Sergeeva notes, the quality of education including e-learning “... does not have a generally accepted formalized description and a particular set of criteria that characterize its essence” [12]. The paper [7] gives a comparative analysis of education quality assessment criteria in the EU (European Quality Improvement System, EQUIS methodology), the US (Association to Advance Collegiate Schools of Business, AACSB methodology), and Russia. Table 2 contains various approaches to the selec- tion of criteria for assessing the quality of online education, presented in the scientific literature.

4 Evaluation of the Quality of E-Learning Using the Project- Based Approach

The authors believe that in a higher education institution the quality of e-learning as a whole or a particular online education program can be evaluated using the project-based approach, i. e. regarding an online education program (or a set of programs) as an in- vestment project and assessing the efficiency of the given project for its core partici- pants – the higher education institution and its students. In this case, we are talking about calculating the commercial efficiency of the project, which is taking into account the benefits and costs of its core participants.

The obtained performance indicators will constitute the objective assessment of the quality of e-learning in a particular higher education institution. These indicators are the response of the socio-economic system to the quality of online education. See Fig- ure 1.

In the classic sense, the efficiency of an investment project is a category that ex- presses “... the compliance of the results and costs of the project with the goals and interests of its participants including, if necessary, the state and the population” [13].

The essence of the process of assessing the efficiency of an investment project is to compare its results and costs. The results and costs of an online education project will be different for each participant and can be characterized not only by a quantitative nature (for example, financial) but also by a qualitative (intangible) nature. Online ed- ucation performance assessment requires the evaluation of all project outputs, both tan- gible and intangible. According to leading Russian experts, the main criterion of the efficiency of an investment project is Net Present Value (NPV) [13].

In the authors’ opinion, when assessing the commercial efficiency of an online edu- cation project for its core participants, it is feasible to apply the concept of evaluating the commercial efficiency of investment projects in the real economy, proposed in the monograph by M.A. Bakumenko [14]. This concept singles out three components of project efficiency evaluation: commercial, strategic, and reputation.

In the case of assessing the commercial efficiency of an online education project for its participants:

the commercial component (СС) shows how a project participant achieves their fi- nancial goals during the project’s design period;

the strategic component (SC) shows how an online education project affects the stra- tegic development of a project participant;

the reputation component (RC) reflects a change in the reputation of a project par- ticipant, resulted from participation in the online education project. See Figure 2.

5 Methodology for Assessing the Quality of Online Education

The essence of the methodology for assessing the quality of online education, proposed by the authors, is briefly described in Table 3.

Following the proposed approach, it is possible to talk about high-quality e-learning in a higher education institution subject to the conditions as follows:

1. 𝐶𝐶𝑖≥ 0, i1,2. I. e. the commercial component for all online education project participants should be non-negative.

2. The online education project will have a positive impact on the process of strategic development of the higher education institution and the student.

3. RCi 0, i1,2. I. e. the online education project will have a positive impact on the reputation of the higher education institution and the reputation of the student (graduate) as a specialist in a particular subject area.

The reputation component of the proposed methodology (for a particular online ed- ucation project participant) can be determined by equation (1), subject to the con- straints (2).

The values of rt and rt are in the range of [– 1; 1] and correspond to a special scale that numerically expresses the attitude of a certain target group towards the OE project participant. For this purpose, one can apply the scale presented in [14; 15]. To define the values of rt and rt, one can use expert technologies combined with qualitative research methods (media monitoring, survey, questionnaire, business conversation, etc.).

If RC > 0, the reputation of the OE project participant has improved after participa- tion in the project; if RC < 0, the reputation of the OE project participant has deterio- rated after participation in the project; if RC  0, the reputation of the OE project par- ticipant has remained the same.

Higher education institution E-learner

Com- mer- cial com- ponent (СС)

CC1 is the value of NPV, reflecting the commercial efficiency of a particular OE program (or a set of programs) over the project’s design period for the higher ed- ucation institution.

The project’s design period equals the du- ration of learning through a particular OE program (if several education programs are included in the analysis, the longest training interval is taken as the design pe- riod).

We are talking about efficiency calcula- tions in the operating phase of the project life cycle. The information base for calcu- lations is the data provided by the finan- cial service of the higher education insti- tution. The process of calculations takes into account the benefits and costs of the higher education institution, determined by a particular OE program (or their to- tal).

The discount rate is determined by the available alternative investment opportu- nities following the modern methodology for assessing the efficiency of investment projects.

CC2 is the expected value of NPV, re- flecting the commercial efficiency of a particular OE program for some hypo- thetical (average) student.

The project’s design period equals the sum of the duration of learning through a particular OE program and five years af- terward (related to the possibility of put- ting the obtained knowledge, skills, and abilities into practice as well as to the rel- evance of this knowledge).

To find the expected value of NPV, the scenario analysis method should be ap- plied. Based on the processing of statisti- cal information and using expert technol- ogies, the cash flows of three scenarios are predicted: optimistic, basic, and pes- simistic ones, and the probability of oc- currence is determined for each scenario.

The process of calculations takes into ac- count the benefits and costs of the student over the project’s design period, due to participation in a particular OE program (including opportunity cost).

The discount rate is determined by the available alternative investment opportu- nities.

Strate- gic com- ponent (SC)

SC1 characterizes the degree to which the OE project encourages the implementa- tion of potential projects in the future (the technique presented in the work [16]

is applied).

SC2 characterizes the possibility of the graduate to advance in the long run. It is defined by experts based on the available statistics. The analog method can also be used here.

Reputa- tion com- ponent (RC)

RC1 characterizes a change in the reputa- tion of the higher education institution, resulted from participation in the OE project.

RC2 characterizes a change in the reputa- tion of the worker (specialist), resulted from participation in the OE project.

The reputation of a higher education institution (as well as the reputation of a spe- cialist) is one of the most significant intangible assets and strongly influences the pro- cess of their strategic development. To preserve (improve) reputation, it is very im- portant to adhere to ethical principles in one’s activities. An organization’s ethical be- havior will enhance its competitiveness (Table 3).

The paper [17] shows that the ethical behavior of firms boosts competitiveness not only of the corporation (firm) but also of the national economy.

To estimate the values of the weight coefficients that define the importance of the opinions of target groups, the authors propose using a scheme based on Fishburn se- quences.

6 Fishburn Sequence-Based Scheme to Estimate the Values of Weight Coefficients

Notably, in equation (1), it is crucial correctly to estimate the unknown values of wt components of the weight vector. The search for these estimates can be based on vari- ous methods and models, including the concept of applying statistical games combined with antagonistic games, described in detail in the monograph by A.V. Sigal [18].

Let us take a closer look at the methodology for estimating the values of wt weight coefficients, based on Fishburn sequences [19], first of all, their particular case − gen- eralized Fishburn progressions (see for example [19]).

Without loss of generality of reasoning, we can assume that the target groups under consideration are arranged in descending order in terms of the importance of their opin- ions (as seen by a certain OE project participant). This indicates that the values of the weight coefficients generate the non-ascending sequence: w 1w 2…w T. Thus, on the components of the weight vector, one or another linear order relation is set by the subjective preferences of a certain OE project participant. Linear order relations were studied in detail by Peter C. Fishburn and are given, for example, in the monograph by R. I. Trukhaev [20]. Let us give definitions of the two most common types of linear order relations (given the case of non-ascending sequences) [20].

A simple linear order relation refers to the relations w 1w 2…w T. A partially strengthened linear order relation refers to the relations wtw1...wt1, t2,T.

Let us set the weight vector W(w 1; w 2;…; w T).The vector’s wt components shall satisfy all the constraints (2). What is more, as the target groups under consideration are arranged in descending order in terms of the importance of their opinions, the values of the weight coefficients satisfy the inequalities w 1w 2…w T.

If in the subjective view of a certain OE project participant, a simple linear order relation holds for the unknown values of the weight coefficients, Peter C. Fishburn sug- gests that the estimates of wt components generate an arithmetic progression, and if a partially strengthened linear order relation holds, then they form a monotonic geometric progression (see for example [20]). The corresponding Fishburn’s equations can be

(10)

easily generalized in the case of monotonic progressions, which leads to the notion of generalized Fishburn progressions (see for example [19]).

We call generalized Fishburn progressions the progressions {w 1; w 2;…; w T}, sat- isfying all the constraints (2): generalized arithmetic Fishburn progressions are arith- metic progressions that satisfy all the constraints (2), generalized geometric Fishburn progressions are geometric progressions that satisfy all the constraints (2).

It can be easily proved that generalized arithmetic Fishburn progressions represent arithmetic progressions of the form

whose common ratio satisfies the inequality x0. For example, the basic properties of generalized Fishburn progressions are given in the monograph [19]. Further gener- alization of the concept of “generalized Fishburn progressions” leads to the concept of Fishburn sequences [19].

Monotonic sequences {w 1; w 2;…; w T} that satisfy all the constraints (2) shall be regarded as Fishburn sequences.

We can estimate the unknown values of wt weight coefficients according to the following three-step scheme based on Fishburn sequences.

Step 1. To define what type of linear order relations the unknown values of wt weight coefficients shall satisfy.

Step 2. To choose a convenient monotonic sequence {a 1; a 2;…; a T} of nonnegative numbers, the sum of which is a positive number, and the sequence itself satisfies the type of linear order relations that the unknown values of wt weight coefficients shall satisfy. Such a sequence {a 1; a 2;…; a T} can be referred to as a sequence generating a Fishburn sequence.

Step 3. To estimate the unknown values of wt weight coefficients by the elements of the corresponding Fishburn sequence by the equation

T

j j t t

a w a

, t1,T .

Notably, as a sequence generating the corresponding Fishburn sequence, one can choose monotonic progressions of natural numbers, including {a 1; a 2;…; a T}{1; 1;…; 1} or {a 1; a 2;…; a T}{T; T–1;…; 1}, as well as such se- quences of natural numbers as Fibonacci numbers, Euclid numbers, Mersenne numbers,

(11)

Fermat numbers (see for example [19]), etc. An arithmetic progression of natural num- bers generates a generalized arithmetic Fishburn progression, while a monotonic geo- metric progression of natural numbers generates a generalized geometric Fishburn pro- gression. It should be noted that any generalized arithmetic Fishburn progression al- ways satisfies the corresponding simple linear order relation, while a generalized geo- metric Fishburn progression satisfies the corresponding partially strengthened linear order relation only if specified requirements hold for the common ratio of the progres- sion (see for example [19]).

Having estimated the unknown values of wt weight coefficients by the elements of the selected Fishburn sequence, one should calculate the desired change in the image (reputation) of the OE project participant, resulted from participation in the OE project, applying the elements of the selected Fishburn sequence to the equation (1) to calculate the RC indicator.

7 Concerning the Creation of a Software Application for Online Education Quality Assessment in Higher School

At present, information technology has become an integral part of management and managerial decision-making. According to the authors, the proposed methodology for assessing the quality of online education in higher schools should form the basis of the corresponding software application, since all the calculations within the proposed meth- odology are rather time-consuming.

Note that the commercial component of the proposed methodology can be found for each online education project participant using special software designed to assess the effectiveness of investment projects and to manage them. Examples of such software solutions well established in the market are Primavera and Microsoft Project, a com- parative analysis of which is given, in particular, in the paper [21]. Aided by these soft- ware solutions, one can plan cash flows for each online education project participant and find the value of NPV or the expected value of NPV.

However, the proposed methodology has two more important specific components:

the strategic component and the reputation one. The presence of these components in the proposed methodology necessitates the development of an appropriate software ap- plication that would facilitate all the calculations.

One of the good tools for modeling software applications is the unified modeling language (UML). See, for example, the works [22, 23]. Moreover, according to B. Dob- ing and J. Parsons, “UML should not be considered exclusively as a language for soft- ware professionals; a greater understanding of UML diagrams and their roles in build- ing systems is needed throughout organizations” [22].

Figure 3 contains a use case diagram that describes the main functionality of the software application proposed for design. “Use case is a high-stage description of what the approach is meant to do, whose purpose is to capture the approach require- ments” [23].

(12)

Figure 3 shows that the software application proposed for design should assess the quality of online education in a particular higher education institution, and (when nec- essary) conduct a similar comparative analysis for several educational institutions.

8 Conclusions

E-learning provides its participants with several undeniable benefits, but it is not free of some essential drawbacks.

With the growing demand for e-learning, the problem of online education quality assessment is becoming increasingly important. This assessment should be carried out based on a scientific methodology using modern tools of economic and mathematical modeling and information technology.

Fig. 3. Use Case diagram of assessing the quality of online education (ОЕ) in higher school The authors believe that in a higher education institution the quality of e-learning as a whole or a particular online education program can be evaluated using the project- based approach, i. e. regarding an online education program (or a set of programs) as an investment project and assessing the efficiency of the given project for its core par- ticipants – the higher education institution and its students. The obtained performance indicators will constitute the objective assessment of the quality of e-learning in a par- ticular higher education institution. These indicators are the response of the socio-eco- nomic system to the quality of online education.

Following the proposed approach, it is possible to talk about high-quality e-learning in a higher education institution subject to the conditions as follows: the commercial component for all online education project participants should be non-negative; the

(13)

online education project will have a positive impact on the process of strategic devel- opment of the higher education institution and the student; the online education project will have a positive impact on the reputation of the higher education institution and the reputation of the student (graduate) as a specialist in a particular subject area.

To estimate the values of the weight coefficients that define the importance of the opinions of target groups, the authors propose using a scheme based on Fishburn se- quences.

The proposed methodology for assessing the quality of online education in higher schools should form the basis of the corresponding software application since all the calculations within the proposed methodology are rather time-consuming.

We believe that the proposed approach to assessing the quality of online education is reasonable. This approach can add to the existing practices for evaluating online ed- ucation quality.
